摘　　要：空气动力控制伺服系统作为姿态控制系统的执行结构,其控制精度对飞行器的姿态稳定性具有重要意义。以某飞行器空气舵摆角位置伺服系统为研究对象,建立了伺服系统的动力学模型,基于Simulink平台搭建系统的仿真模型,通过仿真和相关地面试验,探讨传动间隙对系统静态特性的影响。结合工程经验,优化完善系统角位移传感器安装方案,解决系统角位移测量曲线相位滞后问题。优化后系统空气舵摆角控制精度1.5%,满足姿控系统使用要求,具有较高的工程应用意义和参考价值。As the executive structure of the attitude control system, the control accuracy of the aerodynamic control servo system is of great significance to the attitude stability of the aircraft. Taking the air rudder swing angle position servo system of a certain aircraft as the research object, the dynamic model of the servo system was established through the simulink platform. According to the simulation and related ground tests, the effect of transmission clearance on the static characteristics of the system was discussed. Combined with engineering experience, the system angular displacement sensor installation solution was optimized in order to solve the system angle shift measurement curve phase hysteresis problem. The optimized air rudder angle control accuracy is improved to 1.5%, which meet the requirements of attitude control system and have high engineering application intention meaning and reference value.
